C-5 petroleum resin, also known as C5 petroleum resin, has occupied an important position as tackifying resin. Among them, hot melt adhesives, pressure sensitive adhesives, rubber tires and other fields are the most used. Petroleum resin is suitable for hot melt adhesives, pressure sensitive adhesives and rubber tires. They have good compatibility with SIS, SBS, SEBS, SEPS and other styrene polymers, natural rubber, synthetic rubber and EVA. They also have good compatibility with natural tackifiers (terpenes, rosin and its derivatives), and improve the properties of adhesives to varying degrees. In recent years, petroleum resin has gradually taken the place of natural tackifier because of its high peel bonding strength, good fast adhesion, stable bonding performance, moderate melt viscosity, good heat resistance, good compatibility with polymer matrix and low price.
In recent years, petroleum resin with its peeling adhesion strength, fast adhesion good, stable adhesion function, moderate melt viscosity, good heat resistance, and high polymer matrix compatibility, and low price characteristics, beginning gradually replace natural viscosity-increasing resin and occupy a prominent position.
Characteristics of petroleum resin in adhesive system:
Good fluidity can improve the wettability of the main material. Good stickiness with outstanding initial stickiness function. Excellent aging resistance. The cohesion strength and peel strength reach a good balance. Light colours. Transparent, low odor, low volatile matter.
